The Pureology Strength Cure Blonde toning and repair system in professional 1000 ml sizes — Purple Orchid, Keravis, and Astaxanthin with the Antifade Complex® for blonde, highlighted, or lightened hair at the best value per wash.
Blonde and lightened hair has two problems that most shampoos only solve one of: it goes brassy between appointments, and the lightening process leaves it weaker and more prone to breakage. The Strength Cure Blonde system solves both in the same wash routine. Purple Orchid toning pigments neutralise yellow and brassy warmth using colour-wheel principles — the same technique a professional toner uses in the salon — while Keravis and Astaxanthin rebuild strength and protect the fragile structure that bleaching compromises.
The shampoo and conditioner are designed as a paired toning-and-repair system — not a purple shampoo with an unrelated conditioner added on. Pureology recommends using the system 1–3 times a week (or every third wash), alternating with the regular Strength Cure system on non-toning days for continued repair without over-depositing pigment. The 1000 ml Pro Duo is the same formula at approximately 30% better cost per wash for committed Strength Cure Blonde clients. Aromatherapy: Pear, Rose, and Sandalwood — distinctly different from the original Strength Cure.
The shampoo deposits Purple Orchid toning pigments during the cleanse step while the Keravis and Astaxanthin begin their strengthening work. The conditioner then continues the strengthening and conditioning while locking in the tone deposited by the shampoo — a cool rinse after the conditioner seals the pigment in place. Toning in the shampoo and sealing in the conditioner is how the system maintains consistent, buildable results rather than uneven tone patches from a shampoo-only approach.
Use 1–3 times per week, not every wash. Over-toning builds up and can shift very porous or fine blonde hair ashy or flat. The sweet spot is enough toning to stay ahead of brassiness without over-depositing — and that frequency varies by how porous the hair is and how quickly the warmth returns. Start with every third wash and adjust. On non-toning days, use the regular Strength Cure Shampoo and Conditioner to keep the repair work going.
